Increased PTS, as measured by radiographs and MRI, is correlated with greater risk of reoperation and failure after MAT, with increased MPTS on MRI significantly associated with medial MAT reoperation and failure. There is good to excellent inter- and intrarater reliability for radiographic and MRI PTS measurements, although MRI underestimates radiographic PTS on average 3.3°.
Bi et al. (Mon,) studied this question.
